Why doesn't this code display correct?

Question

Code :

i = 0
while i<=10:
print(i)
i += 0.1

It displays other numbers than 0.1 0.2 0.3 0.4 and ...

How can I fix this?

Answer 1

Format the output to show only 1 digit following the decimal point

i = 0.0
while i <= 10.0:
print( f"{i:.1f}" ) # .1 means only 1 digit following the decimal point
i += 0.1

Answer 2

The decimal point makes conversion to `int` failed. Looks like it is necessary to first convert the string into a `float`, then convert the `float` value into `int`.

n = 12.345 # float
sn = f"{n:.1f}" # string
print( sn )
print( int( float( sn ) ) ) # to float first, then to int.

What is your excepted output?

Ipang Thanks alot!

Answer 5

Ipang sorry for asking again, how can i do i = f"{i:.1f}" ?

it becomes an str value and when i put i = int(i) it shows another error
